Three medicinal plant Aegle marmelos, Lawsonia inermis, Albizzia libbeck were extracted by soxhlet apparatus using petroleum ether, ethanol, chloroform and aqueous as solvent. Among those extract, the petroleum ether was considered as effective one. The extracts were subjected to preliminary phytochemical screening and the three plants with four extracts were tested against three gram positive bacteria (B. cereus, B. subtilis, S. aureus) and three gram negative bacteria (E. coli, P. vulgaris, and P. aeruginosa) by disc diffusion method. Maximum inhibition (3.8 cm) was recorded in Lawsonia inermis. It also showed inhibitory action against all the six pathogen tested. The zone of inhibition of the extracts was compared with the standard antibiotics Streptomycin and Spectinomycin. The study suggests that the plant is promising the development of phytomedicine for antimicrobial properties.
采用索氏提取器，以石油醚、乙醇、氯仿和水为溶剂，对三种药用植物印楝、散沫花、阔荚合欢进行提取。在这些提取物中，石油醚提取物被认为是有效的。对提取物进行了初步的植物化学筛选，并通过纸片扩散法，用这三种植物的四种提取物对三种革兰氏阳性菌（蜡样芽孢杆菌、枯草芽孢杆菌、金黄色葡萄球菌）和三种革兰氏阴性菌（大肠杆菌、普通变形杆菌、铜绿假单胞菌）进行了测试。散沫花提取物的抑菌圈最大（3.8厘米）。它对所有六种受试病原体也均有抑制作用。将提取物的抑菌圈与标准抗生素链霉素和壮观霉素进行了比较。该研究表明，这种植物有望开发出具有抗菌特性的植物药。
